CARBURETER.

S PECIFIGATION forming part of Letters Patent No. 688,408, dated December 10, 1901. Application filed January 21, 1901. Serial No. 44,196. (No model.)

(for which I .have made application for pat-j ents in Switzerland, dated November 17 1900 in Italy, dated December 19, 1900; in Austria, dated December 20, 1900; in France, dated December 21,1900; in Belgium, dated December 21, 1900; in Hungary, dated December 21,

1900; in Denmark, dated Decernber2l, 1900;: in Germany, dated December-22,1900; in Sweden, dated December 22, 1900, and in Great Britain, dated January 1, 1901, No. 51,) of which the following is a specification.

My invention relates to an improved construction of gas-producing apparatus which principally differs from others used for a like purpose, inasmuch as there is always comparatively little crude liquid, (liquid hydrocarbon or gasolene,) as well as an exceedingly small quantity of gas, present in the apparatus. The gas-generator is also completely surrounded by water, which, warmed automatically, can be retained at any suitable temperature for the purpose of facilitating the gasification of crude liquids diff cult to evaporate, and which water-jacket practically also obviates the danger of eXplosious-for instance, in case of firesas should the small quantity of crude liquid in the interior become hot it will quickly gasify and owing to the increase inthe pressure could escape into the atmosphere through anopening formed in the water-jacket, the latter therefore obviating a sudden large and thus dangerous inward heating. Should even extraordinary circumstances cause an explosion, it would not be so disastrous as in other systems where a large quantity is present.

The apparatus works very economically and rationally, loss of gas being entirely prevented, and allcrude liquids, even such which are difiicult to gasif y, are uniformly converted to gas.

The apparatus is also very easy to manipulate, takes up comparatively little space, and can be installed in rooms occupied by people Without danger to them, and being driven by of crude or explosive liquid weight instead of motor power the working expense in this respectis m7.

I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a front vie w;Fig. 2, a side view;

Fig. 3, a cross-section'at line AB of Fig. 2;

Fig. it, a cross-section at line C D of Fig. 1, and Fig. 5 a View of a detail.

Similar characters refer to similar parts throughout the several views.

In carrying out my invention I employ i thelower part of the apparatus a fan 1, which, as shown inFig. 2, is rotated by means of a weight actuating a rope-drum, draws inair at 3, and delivers it at 4. Above this fan a gas-generator 5 is employed, which is surrounded by a water-jacket 6. The said gasgenerator is internally formed with disks 7,

which divide it in various gasifying-compartments having at the bottom ports 8, allowing the crude liquid to passfrom one compartment to the other. Between the said disks other disks 11 are secured upon a shaft 10. The sides of these disksv are faced with some porous material, such as felt, and also formed with ports and buckets 9. (See more particularly Fig. 3.) The said shaft is rotated from the fanshaft by chain-gearing 12. Above the said gas-generator the water vessel 14 of a pressure-regulator is formed, through the water of which project the ends a and b of a pipe 13, one of which leads tothe fan and the other to the gas-generator at 15, whilea branch pipe 17, furnished with a tap 16, leads also to the gas-generatorat 18 and to the gas-delivery pipe 19. The gas-generator communicates also with the pipe 20, which supplies the crude liquid used and can be cut off by a valve 22, actuated by a float 21. The said pressure-regulator consists of an inverted vessel 23, over which reaches a double-armed lever 25, fulcrumed to the regulator at 29. The said inverted vessel is adapted to rise and push against the long arm of the lever 25, while the shortarm is connected by a rod 26 to an angular lever 27, which is shaped to form a brake 28, adapted to act upon a pulley 29, secured upon the shaft 10.

The crude liquid in the gas-generator is tempered by heating the water in the said jacket by a gas-flame fed from the pipe 19 by means of the branch pipe 30. The water-jacket 6 also communicates at 32 and 33 with a pipe 31, which has an enlarged part 34, serving as a heating-surface and containing a divisionplate, so that the water passes over a comparativelylarge heating-surface. The burner 36 has aby-pass, and the flame is regulated by the tap 38, furnished with a lever 39, placed under the influence of a spring 40 and that of the electromagnets 41, which latter operate the armature 42, connected with the said tap-lever. Into the circuit 43 of the electromagnets a thermometer 44 is inserted, the quicksilver of which whenat a certain height causes the circuit to be closed and at a certain depth to be opened. The thermometer is located in a double-walled vessel 45, secured to the jacket 6, and the space between the said walls communicates with the latter, so that the water in the jacket 6 has access to the said space, and its temperature controls the state of the thermometer. This device is so arranged that when the quicksilver column of the thermometer is at a certain height the electric circuit closes and the gasfeed will be cut off by the armature actuating the tap 38, while when the quicksilver column falls the spring 40 will open the tap 38, owing to the electric circuit being broken, and the flame will be lighted through the bypass. The device described may, however, be so modified that when the electric circuit closes gas will be admitted and cut off when the circuit breaks. This modification is principally used for crude liquids diflicult to evaporate.

In starting the apparatus described the crude liquid (gasolene and the like) is admited into the gas-generator 5 and its level regulated by the float 21. The rope-drum is then set in motion, which causes the fan 1, shaft 10, and disks 11 to rotate, the latter at a higher speed than the former. The buckets 9 rise and empty the crude liquid over the sides of the disks 10, faced with porous material and formed with ports, which latter allow the liquid to pass from side to side of the said disks. The gas is generated, as well known, byevaporation, the fan 1 supplying through pipe 13 the necessary air, which passes the inverted vessel 23 of the pressure-regulator 14. The inverted vessel 23 rises and falls in accordance with the variation of pressure therein and at a certain excess of pressure pushes against the lever 25, which causes the brakelever 28 to be applied to the pulley 29, and

thereby the supply of air accordingly reduced,

and thus the gasification retarded or interrupted. The branch pipe 17 permits of mixing with the gas issuing at 18 an additional volume of air, if deemed necessary.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is

1. A gas-producing apparatus, consisting of a gas-generator divided into compartments which communicate with each other, disks contained therein secured upon a rotary shaft and formed with buckets, apertures and faced with porous material, the said gas-generator communicating with a fan which supplies the air required and being geared up with the said disk shaft and the said cups adapted to raise and empty the liquid hydrocarbon, over the said rotating disks forevaporation thereby, all substantially as aud for the purpose set forth.

2. In a gas-generator formed with compartments containing rotary disks with ports, buckets and sides faced with porous material and communicating with a fan geared up with the shaft of the said disks, in combination, an inverted vessel capable of rising and falling in a water vessel containing air-pipes leading respectively to the said fan and generator, a double-arm ed lever fulcrumed above the said inverted vessel and connected to a brake-1ever and a brake-pulley on the said disk shaft, the said inverted vessel being adapted to rise at a certain excess of pressure therein and through the said double-armed lever apply the brake-lever to the respective pulley and thereby retard or interrupt the air-supply and thus the gasiflcation in the generator, all substantially as and for the purpose set forth.

3. In a gas-producing apparatus having a gas-generator surrounded by a water-jacket,

in combination, a gas-burner and tap having a by-pass, the flame of which is adapted to heat a portion of the water-circulating pipe of the said jacket for the purpose of tempering the water in the latter, a lever on the said tap under the influence of a spring and an electromagnet and a thermometer subjected to the action of the tempered water in the said jacket, and electrically connected with the said electromagnet, which thermometer at a certain maximum state closes and at a certain minimum state opens the circuit of the said electromagnet and thus allows the said spring to open and the said electromagnet to close the said tap respectively, all substantially as and for the purpose set forth.
